SAN LEANDRO — Sheriff’s homicide investigators have identified a possible suspect in the Monday slaying of a 41-year-old man inside a house in unincorporated San Leandro, authorities said Tuesday.

The name of the suspect, a man, has not been released nor has the name of the victim.

Sheriff’s Sgt. Ray Kelly said it appears the suspect and victim knew each other but the motive for the killing remain unknown.

The man was found dead about 1:45 p.m. Monday inside a house in the 16000 block of Selborne Drive. A blood trail from outside led to the house, but it is not clear how long before the man was found the trail was left.

The victim apparently did not live at the house and it was not known if the suspect did, authorities said.

Kelly said there are indications that both a gun and knife were possibly used in the killing but the exact cause of death has not been determined.

Anyone with information about the killing or who has residential video surveillance from the area is asked to call detectives at 510-667-3636 or 510-667-7721.
